Following up on the removal of ARM old-ABI support, I've applied this
patch to merge sysdeps/unix/sysv/linux/arm/eabi into
sysdeps/unix/sysv/linux/arm. I verified that symbol versions and
disassembly of the libraries were identical before and after the patch.
I'll deal separately with merging sysdeps/arm/eabi into sysdeps/arm.
